ACA has chapters in Queensland, South Australia, Western Australia and a member association in Victoria. Several chapters are being established in New South Wales and will be operational by 1 July 2020. All ACA members are invited to join their State chapter or member association. The role of the chapter is to provide members with local professional development, supervision and support functions. Chapters also advise the ACA national office of any relevant State issues, and may assist the ACA with local lobbying.
